Double-acting burst disc SAFE-SHEAR™

Technetics Group will design, manufacture, and test a precision burst disc assembly for your application. Our burst discs are capable of precise and reliable burst settings from low pressures or vacuum (1 psi pressure differential), up to 10,000 psi. All this while maintaining up to 1% full-scale precision and infinitesimal leakage, regardless of infinite pressure and temperature cycles, dynamic environments, and harsh media. Precision Burst Discs The SAFE-SHEAR™ Burst Disc is designed to set and verify exact rupture pressure in a non-destructive test. The BELLEVILLE spring snap-over trigger mechanism relies on a proprietary solution to achieve extreme accuracy. Diaphragm thickness resists 2 to 3 times the burst set pressure, and is capable of infinite cycling without degradation to fatigue. Cycling may be up to 98% of set burst pressure without altering performance. It has been demonstrated that Belleville type burst discs are one order of magnitude more accurate than Frangible type burst discs.
